IMPRQVZEMENT IN PLOW-ATTACHIMENT, (DOUBLE-TREE.)

The Schedule referredV to in these Letters Patent and making part of thesame.

To all whom it may concer-n: I

Be it known that I, L. E. MOREY, of Vandalia, in the county of Fayette,and State of Illinois, have invented a new and improved Plow-Attachment;and I do hereby declare that the following is a full, clear, and exactdescription of the same, reference being had toA the accompanyingdrawings, forming a part of this specication, in which- Figure 1represents a liat view of a plow-attachment, constructed according to myplan, and

Figure 2 represents the position of theattachment in which it is used,and its manner of attachment to the plow.

Similar letters of reference indicate corresponding parts in bothigures. A

This invention consists in a triangular construction of bars, boltedtogether, and provided with loops or hooks, whereby three horses may beas readily attached to a plow as two are attached by the ordinary means.

In order that others may be better enabled to understand theconstruction and operation 'of my invention, I will proceed to describeit with reference to the drawlngs.

B' B are two bars of wood, or other suitable material, having theirupper ends lapped and bolted together, and their lower ends extendingdownwards, and so diverging as to form an obtuse angle between them.

At points c c, two-thirds of the length of said bars below the junctionor point b', there crosses a horizontal bar, A, the ends of which aresecurely bolted to the bars B B', thereby forming a triangularstructure, as illustrated at ig. 1. Y

At the centre of the barrA is riveted or bolteda loop,

for the, purpose set forth.

a, for connection of the structure with the plow C, as

Aillustrated at iig. 2.

At the junction and lower extremities of thebars B B' are riveted orbolted loops, hooks, or staples b bb, t-owhich the horses are hooked.

There being twice the vertical distance between the loop-a and the. loopor staple b', situated at the apex or junction ot the bars B B', asthere is between said loop a and the loops or staples b b, upon thelower ends of said bars, the centre horse will have 'suiiicient leveragethereby to make the draught about uniform, and keep the triangularstructure in a perpendicular position, or the hook b directlyperpendicular to a line dra-wn between the hooks b and b.

Similar hooks, loops, or staples may also be supplied at the points c c,where the bar A is secured to the bars B and B', so that the device mayalso be used as an ordinary double-tree, when itis desirable to use twohorses instead of three, and to which said hooks, loops, or staples thetwo horses may be hooked. 'Y

The triangular structure maybe replaced bythe use of ,a horizontal bar,from the central portion of which projects a perpendicular bar, asillustrated by the diagram, Figure 3, and' upon which are secured thehooks,

loops, or staples, a b b b.

What I claim as my invention, and desire to have secured by LettersPatent, is

A plow-attachment, having four connecting-points, a, b, b, and b',arranged substantially as herein described,
